In this article, we will see how to use Web services in a real-time Web application. Even though Web services are very powerful and based on open Internet protocols such as XML, HTTP and SOAP (that accounts for platform independence), using them in a real-time Web site requires careful consideration of performance implications. For example, if before showing a particular page you try to call out two or three Web services across the Internet to get data, the responsiveness of the site is going to be severely impacted. At the same time, you cannot avoid calling out to Web services to get the data you want. However, if you carefully plan your Web application, you can take advantage of the functionalities of the Web services without impacting the performance of the application.

In this article, we will consider the very common example of a Stock Ticker application and understand how to use features such as asynchronous Web services, Windows service applications, server-based timer components, and .NET XML API classes to create high-performance, scalable, and flexible applications.Regards,
